Getting Motion Detect Sensitivity from VN-V686
Format /api/param?camera.detection.level
Example of response camera.detection.level=20&200 OK
Interpretation Acquire the motion detect sensitivity. A value between 0 to 100 will be returned. The larger the
value, the higher will be the sensitivity.

Setting Motion Detect Sensitivity for VN-V686
Format /api/param?camera.detection.level=data
Example of response camera.detection.level&202 Accepted(camera.status=save)
Interpretation Change the motion detect sensitivity. Specify a value between 0 to 100. The larger the value, the
higher will be the sensitivity. The sensitivity is 11 steps internally. The change is saved by the API,
camera.status=save. If the change is not saved, the setting is restored by reboot.

Getting Motion Detect Mask from VN-V686
Format /api/param?camera.detection.area
Example of response camera.detection.area=000102030405060708090001&200 OK
Interpretation Acquire the mask of motion detect. 24 ASCII characters will be returned.
The screen of VN-V686 is made up of 12 x 8 = 96 blocks, and mask can be set to on/off for each block. This
information can be represented in 96 bits = 12-byte hexadecimal. (Response is returned in ASCII character strings.
Therefore, 24 characters will be returned.) The bit string will appear as follows when mask is set to off for the top left
block only.
10000000 00000000 00000000 ,,,
Storage in bytes will begin from the LSB and represented in a hexadecimal value as shown below.
01 00 00 00 00 00 00 00 00 00
The hexadecimal value denotes the 24 ASCII characters acquired via this API that are expressed in ASCII codes. For
example, the following character string will be returned when only the top left and bottom right blocks are masked.
camera.detection.area=010000000000000000000080
